Looking at the roots, I'd be wary about putting them in the compost. The tiny pieces which are dark have new growth on them. You might cause yourself no end of problems if all the little bits grow. It takes a lot of heat in a compost heap to kill roots on bindweed so I avoid putting any in the compost and this looks similar.
Thanks for the replies..... I am a gardener and I'm keen to broaden my knowledge. If clients have the same problem I will be able to enlighten them. I like to read up on things.... bit difficult if you don't know what it's called!!!
I think it helps to know weed names so we can make educated choices about what, if any, to leave as host plants for larvae of moths, butterflies, pollinators and predators of pests or, as in this case, what not to put on the compost heap.
We have ragwort on our plot and need to pull it out before it sets seed as we have horses next door and cattle on the other 3 sides. Even so, we've been checking each plant for caterpillars of the cinnabar moth before we fork them out.
